Everything seems to work. * o DPMSGCMD_REQUESTNEWPLAYERID & DPMSGCMD_NEWPLAYERIDREPLY * Barely works. This needs to be completed for sessions to start. * o A small issue will be the fact that DirectX 6.1(ie. DirectPlay4) * introduces a layer of functionality inside the DP objects which * provide guaranteed protocol delivery. This is even if the native * protocol, IPX or modem for instance, doesn't guarantee it. I'm going * to leave this kind of implementation to as close to the end as * possible. However, I will implement an abstraction layer, where * possible, for this functionality. It will do nothing to start, but * will require only the implementation of the guarantee to give * final implementation. * * TODO: * - Implement mutual exclusion on object data for existing functions * - Ensure that all dll stubs are present and the ordinals are correct * - Addition of DirectX 7.0 functionality for direct play * - Implement some WineLib test programs using sdk programs as a skeleton * - Change RegEnumKeyEx enumeration pattern to allow error handling and to * share registry implementation (or at least simplify). * - Add in appropriate RegCloseKey calls for all the opening we're doing... * - Fix all the buffer sizes for registry calls. They're off by one - * but in a safe direction. * - Fix race condition on interface destruction * - Handles need to be correctly reference counted * - Check if we need to deallocate any list objects when destroying * a dplay interface * - RunApplication process spawning needs to have correct syncronization. * - Need to get inter lobby messages working. * - Decypher dplay messages between applications and implement... * - Need to implement lobby session spawning. * - Improve footprint and realtime blocking by setting up a separate data share * between lobby application and client since there can be multiple apps per * client. Also get rid of offset dependency by making data offset independent * somehow. */#include <stdarg.h>#include "winerror.h"#include "windef.h"#include "winbase.h"#include "wine/debug.h"#include "dplayx_global.h"
